According to the technical scheme, the butterfly valve comprises a valve body, connecting flanges are arranged at the two ends of the valve body, a butterfly plate is arranged in the valve body, a valve rod is fixed to the butterfly plate, the valve rod is movably connected with the valve body, and two clamps corresponding to the connecting flanges in position are arranged at the top of the valve body. The butterfly valve convenient to connect with the pipeline comprises a valve body, two hoops are arranged on the valve body, each hoop comprises an upper hoop sleeve and a lower hoop sleeve, one end of each upper hoop sleeve is movably connected with the end of the corresponding lower hoop sleeve, and the other end of each upper hoop sleeve is fixed to the end of the corresponding lower hoop sleeve through a fastening bolt. When the butterfly valve is used, the two hoops are arranged on a flange on a pipeline in a sleeving mode to achieve positioning, then the driving rod is rotated, the valve body can be lifted by winding the pull rope, finally the connecting flange moves into the hoops and is aligned with the flange on the pipeline, the butterfly valve and the pipeline can be conveniently installed, operation is labor-saving and safe, and operation can be completed only by one person.

    本发明公开了一种方便连接管道的蝶阀,其技术方案是:包括阀体,阀体两端均设置连接法兰,阀体内设有蝶板,所述蝶板上固定有阀杆,所述阀杆与阀体活动连接,所述阀体顶部设有两个与连接法兰位置对应的卡箍,所述卡箍包括上箍套和下箍套,所述上箍套一端与下箍套端部活动连接,所述上箍套另一端通过紧固螺栓与下箍套端部固定,一种方便连接管道的蝶阀有益效果是:通过在阀体上设置两个卡箍,在使用时先将两个卡箍套置在管道上的法兰上实现定位,再转动驱动杆即可通过收卷拉绳的方式将阀体吊起,最终使连接法兰移动至卡箍内并与管道上的法兰对齐,方便了蝶阀与管道的安装工作,操作省力安全,仅需一人即可完成操作。
